Solved: what is the impact of CRC errors on network performance?

I need to know how the users of the network will experience the CRC errors.

Hi there,

The device which detects a CRC error with a frame will silently drop it. It will be up to the clients involved with the transmissions to detect the fact it did not make it to its destination and request a retransmission. Retransmissions are part of the TCP process and in themselves are not a bad thing, but when a traffic stream becomes consumed by retransmissions requests, the volume of payloads within a time frame will drop off which will manifest itself as a drop in throughput. This disruption will also affect time-sensitive applications such as voice and will be detected as high latency and jitter.

cheers,

Seb.

- They won't because data integrity is guaranteed by the relevant network layer.
